Yes. I must say that this is rather pleasant.
I feel so much lighter.
I am very happy with my recovering an ability to socialize.
I'm gradually recovering an intellectual capacity that I thought might be lost forever.
I have a long way to go, but this is a journey to be enjoyed.

Casanova was advised to his memoirs as therapy, feeling as he did that life either sent you mad or made you die of grief.

Hi Sigi.
I added a few things for you.
I experience only two side effects from prazosin.
1. Mild dizziness
2. Reduced sex drive.

The more I improve, the more I realize how sick I am. In the past, I tended to overrate my partial improvements. As best as I can determine, I am now about 25% improved. I am not comfortable rating myself any higher at this point.
Global improvement:25% above baseline relative to remission.
Symptom Improvement:1. More mental and physical energy
2. Increase in the ability to experience pleasure and reward.
3. Increased desire to socialize.
4. Reduced social anxiety.
5. More talkative.
6. Improved ability to read and comprehend.
5. Increase in motivation to initiate activities.
6. Fewer awakenings during the night.
7. Improved short-term memory and long-term recall.
8. Increased intellectual capacity / IQ.
9. Less tendency to feel cold.
10. Less tendency to stare into space.
11. Reduced appetite / food intake.
12. Increased interest.
13. Increased decisiveness.
14. Increased self-esteem.
15. Reduced psychomotor retardation.

Hi Scott,
Did you decide to stay at 6mg or are you going to try a higher dose?

I have been taking 6 mg for quite a few weeks. I had thought to experiment with higher dosages, but never followed through with it. Perhaps I should try it just to be sure that I am not missing out on anything. What do you think? How do you think I should go about it? I have 1 mg pills to work with. I am currently taking one 2 mg pill t.i.d.

Perhaps you could start out by increasing your night time dose. You might sleep better and hopefully 'sleep through' any dizziness (assuming you don't get up for a pee!)

> Eddy, does Scott's response to prazosin surprise you?
I don't know if Ed is surprised, but I certainly am. However, there is a reason for everything - we just don't know it yet. I can't be unique. I'm sure others will respond to prazosin as well. I haven't recommended it to anyone yet, though. I am hoping that some people will try prazosin on their own initiative based upon my reporting.
It may be that the antagonism by prazosin of NE alpha-1b receptors reduces neuronal activity in circumscribed areas known to be hyperactive in depression, including subgenual cingulate and nucleus accumbens. These areas just so happen to have populations of these receptors.
Interestingly, prazosin antagonism of NE alpha-1b receptors reduces activity in areas known to be stimulated by amphetamine and cocaine. I bet prazosin can aid in treating addiction to these to stimulants. It is hypothesized that global reduction in 1b receptor activity is partly responsible for producing depression. However, the interactions between circuits is complex. I don't think prazosin will be a successful treatment for everyone. I am interested in characterizing the subtypes or symptomatological profile of people who will respond to prazosin.
For now, I would like to propose the idea that prazosin, in combination with antidepressant medication, will help resolve depressions that evolve due to developmental PTSD wherein the PTSD is occult, operating in the background and driving the depression. This would indicate that people who suffered physical abuse, emotional abuse, or neglect early in life would have a good chance to respond to prazosin.
I am really not terribly interested in performing intense research regarding prazosin and its neurobiology right now. I am too involved in enjoying its results.

Okay. That's a good plan. Thanks.I am all but convinced that 6 mg is the optimal dosage for me, but I don't want to miss out on a more robust therapeutic effect and the achievement of remission. Actually, I began to respond to 3 mg, but found that my mood was somewhat variable. I raised the dosage by 100% to 6 mg just to have some headroom. I immediately gleaned an antidepressant response of greater magnitude without mood lability. I might increase the dosage by another 50% to 9 mg. The worst thing that happens is that I get dizzy.

I will try it at some point.
When it was used as a blood pressure med there must have been some somewhat depressed people who benefited from it?

I wouldn't know. I guess the effect couldn't have been that robust, or it would have been noticed. Prazosin was found to be effective for PTSD by accident at a VA hospital. It probably does not help with MDD or BD as monotherapy.

Prazosin works by raising dopamine (DA) levels in the synaptic cleft in the prefrontal cortex and inhibiting extracellular DA concentrations in the nucleus accumbens

Oh dear, I do this too! My psychiatrist says I am "too optimistic" (LOL) and subconsciously trying to be a perfect patient, but not in a helpful way. Thought I was the only one!
On another note: was your blood pressure high, normal or low to begin with and how has it changed on Prazosin? Do you have dizziness with your other meds? I am interested in Prazosin, but having naturally low-mid blood pressure and dizziness on current meds I think it may be too much.
And do you think a MAOI/Prazosin combo would allow one to consume a less restrictive diet?

> Do you have dizziness with your other meds?
Parnate does cause some dizziness. I have noticed that it is somewhat worse with the prazosin, but not much. I experienced more significant dizziness immediately after starting prazosin, but it very quickly mitigated.
> I am interested in Prazosin, but having naturally low-mid blood pressure and dizziness on current meds I think it may be too much.
You'll never know unless you try it. Dizziness has not been a deal-breaker for me. I do get occasional orthostatic hypotension if I stand up too fast.
What attracts you to prazosin? What is it about your particular case profile and case history that leads you to believe that prazosin is worth trying?
What drugs are you currently taking?
> And do you think a MAOI/Prazosin combo would allow one to consume a less restrictive diet?
I don't have enough information to make an educated guess. I do know that phentolamine (Regitine) is the drug of choice to treat a hypertensive crisis. It is a non-selective NE alpha receptor antagonist (alpha-1 and alpha-2). Prazosin is selective for alpha-1. A few things I found reported that prazosin attenuates the tyramine pressor effect, but I haven't found anything reporting its use in a hypertensive crisis.
I would advise starting prazosin at a dosage of no more than 3 mg/day. I take it 3 times a day because it has such a short half-life, although twice a day should work, too. You could begin treatment with 1 mg at night. 3 mg/day was almost enough for me to glean a stable antidepressant effect from. It was obvious that I would lose the effect at the end of a dosing period, so I increased the dosage to 6 mg/day. This is still a low dosage. People go up to 20 mg/day to treat hypertension. Even 40 mg is considered safe.

I have bad nightmares and a history of childhood trauma. Also our med combo is kinda similar and from what you've said, it appears to be helping you tremendously. Though come to think of it you've added Parnate as well.
I suspect my psychiatrist is going to want to change a med or two in a couple of months.
> What drugs are you currently taking?
Nortriptyline 100mg
Lamictal 200mg
Lithium 125mg
Melatonin 3mg
Aspirin 100mg for TCA-induced heart issues
The usual supplementsAs an aside, I recently was prescribed a muscular skeletal relaxant called Norflex for short-term treatment of a neck injury. I'm interested in seeing what, if any, effect it has on my depression. Wouldn't mind some "mild euphoria".

Ah, so we're dealing with a different doseage regime. That should make quite a difference in terms of side effects.
Thanks Scott.

It did initially Sigi, but less so now. I read a bit about how it might augment noradrenergic ADs.

Hi Scott,
I think it's impossible to predict what the optimal dose will be. Prazosin is hardly a standard drug for depression. Perhaps a higher dose might be much better, I really have no idea.
